We're going to need to amplify the pointer and that's going to require access to our AddressSpaceManager, which we only get non-statically through our LargeAlloc. This patch unto itself makes the world slower, perhaps because Clang can't see the certainty of aliasing of the static and non-static paths to the same structure. However, when we also de-static external_pointer, that goes away and things return to the status quo ante.
